Concept: When factoring polynomials, we are doing reverse multiplication or “un-distributing.” Remember: Factoring is the process of finding the factors that would multiply together to make a … Factoring Quick Check . Look for the factors of the “ac” that add to coefficient “b.” As factoring is multiplication backwards we will start with a multipication problem and look at how we can reverse the process. To factor a trinomial in the form x 2 + bx + c, find two integers, r and s, whose product is c and whose sum is b. Rewrite the trinomial as x 2 + rx + sx + c and then use grouping and the distributive property to factor the polynomial.
